3. REQUIREMENTS
3.1 Materials.
3.1.1 Type I. Type I varnish shall be a straight thermosetting phenol-formaldehyde varnish
free from rosin or rosin derivatives, but may include the use of other materials to improve
the leveling, flexibility and adhesion of the coating.
3.1.2 Type II. Type II varnish shall be a straight thermosetting phenol-formaldehyde
varnish free from added plasticizers, rosin or rosin derivatives.
3.1.3 Type III. Type III varnish shall be a mixture of bisphenol epoxide and phenol-
formaldehyde resins. It may include other materials to improve the leveling of coating.
3.2 Solvents.
3.2.1 Thinner. A thinner shall be supplied with the varnish so that the varnish can be
reduced to the proper usable viscosity prior to application. The varnish and thinner
delivered as a lot shall be furnished in quantities proportional to the ratio recommended by
the manufacturer to produce the specified film thickness after baking.
3.2.1.1 Solids content. Type I and II varnish, when diluted with the supplied thinner shall
have a viscosity of 30 centipoises at 70o ± 2o F, and a minimum solids content of 29 percent.
